RADIATOR CAP.

Application filed April 5,

To all whom it may concern:

Be it known that we, IsrnoR M. JACOBS and VVILLIAM CRAMER, citizens of the United States, residing, respectively, at the 5 city of Kansas City, county of Jackson, State of Missouri, and at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Radiator Caps, of which the fol- 10 lowing is a specification.

This invention is a radiator for motor vehicles and boats, aeroplanes, and the like. Its purpose is analogous to that of the radiators described and shown in the patents of the same inventors, 1,294,807, dated February 18, 1919: 1,314,521, dated September 2, 1919: 1,319,871, dated October 28, 1919.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts Wherever they occur,

Figure 1 is a front elevation;

Figure 2 is a side elevation;

Figure 3 is a top plan view; and

Figure 4 is a detail of the cap (partly in section).

The radiator-cap 1 is provided with an opening 2. Inverted, the cap can be used as a funnel, which is quite a convenience. 3 The inside or true radiator 3 is covered by the outside or false radiator 4. The cap 1 is attached to the outer radiator 4.

The lower members 5 of the radiator 4: are bolted at 6 to the chassis 7. The upper member 8 is bolted at 9 to the members 5.

The cap 1 is made removable, not only so that the interior cap 10 can be reached, but, also, for use as a funnel for pouring water into radiator 3.

The cap 1 is provided with a lug or flange 11, which slightly overlies the radiator top. Rivets 12 secure plate 13 and leaf spring 14 to cap 1. Leaf spring 14 is provided one end of which is secured to the inner end of 45 the cap 1 and the opposite end slidably engaged with the inner face of the radiator 4.

Latch 15 is adapted to slide in hole 16 in extension 17 being forceable backward to disengaging position by pushbutton 18, whereupon the cap 1 can be removed from radiator 4. When replaced, leaf 1 1 is first inserted in the position shown in Figure 4; then lug 11 is in the place shown in that figure; then extension 17 is allowed to as- 1920, Serial No. 371,456.

sume the position shown in that figure; then pressure is released from button 18 and spring 19 forces the same out of engagement with spring 20, which is attached by screw 21 to latch 15. Spring 20, which is attached by bolt 22 to the inside of cap 1, then forces latch 15 to the position shown in Figure 4.

Having thus described this invention, we hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that man minor changes may be made therein without departing from the spirit of this invention or the scope of the following claim We claim:

1. The combination with a radiator having a filling o ening therein, of a casing arranged to enc ose said radiator and having an opening therein disposed in alignment with the filling opening thereof, a hollow cap member having its lower end shouldered to removably seat within the opening in said casing, the upper end wall of said cap having an opening therein in communication with its hollow interior whereby said cap may be inverted for use as a funnel during the filling of said radiator, and a latching means carried by said cap member and adapted to engage the under side of the wall of the opening of said casing for maintaining said cap against accidental displacement from its operative position.

2. The combination with a radiator having a filling opening therein, of a casing arranged to enclose said radiator and having an opening therein disposed in alignment with the filling opening thereof, a hollow cap member having its lower end shouldered to removably seat within the opening in said casing, the upper end wall of said cap having an opening therein in communication with its interior whereby said cap may be inverted for use as a funnel during the filling of said radiator, a resilient latching means carried within said cap member and adapted to engage the under side of the wall of the opening of said casing for maintaining said cap against accidental displacement from operative position, and means projecting through the side wall of said cap member for the manipulation of said latching means to and from operative position.

3. The combination with a radiator having a filling opening therein, of a casing end of said cap member and adapted to engage beneath the under side the opening in said casing, and a latching means carried within said cap member, said latching means being disposed at a point diametrically opposite the said projection and adapted to be removably engaged beneat-h the under side of the wall of the opening in said casing.

In testlmony whereof we hereunto affix.

our signatures.
